In which case I look forward to the day I break my neck on the German footbridge, as Lewisham deliberately removed all the higher handrails on this footbridge on the pretext that it allowed a foothold for some yobbo to climb onto the outside of the bridge, which would be dangerous for him!!

As for the mural - just jet spray it away - what is wrong with clean brickwork showing?
The metal cladding for the underpass sounds expensive - cant they just damp-proof and seal the original brickwork and plug the leaks?

Plus this underpass needs to have disability access - the pavement is wide enough now on perry vale to provide a ramp, and a lift can be installed on the other end as discussed before.
